摘要
近年来矿区谐波污染日益严重,为提高煤矿电能质量,提出了将载波相移,即正弦脉宽调制技术与FBI级联式多电平变流器结合起来应用到矿用高压大功率SAPF中,既可以满足高压大功率的要求,又可以在较低开关频率下实现较高的等效开关频率,具有良好的实用价值。该方案经仿真实验,验证了其正确性与有效性,具有良好的效果。
In recent years, the harmonic pollution is worsening in the coal mine, which has become a priority problem to solve. In order to improve the power quality, proposes the carrier phase shift, that is sinusoidal pulse width modulation technique combined with the FBI cascade multi-level inverter applies to mining high voltage power SAPF. It not only can meet the high power requirements, but also can realize the higher equivalent switching frequency at the lower switching frequency, which has good practical value. The simulation test verifies the correctness and validity of this proposal.
